The Smooth-Cast™ 325, 326 & 327 ColorMatch™ Series plastics are urethane resins that were developed specifically for adding color pigments and fillers to achieve true color representation or filler effect. The ColorMatch™ Series is formulated “color neutral”. Small amounts of pigment will yield accurate, vivid colors from cured castings using So-Strong™ tints, UVO™ pigments or Ignite™ color pigments. The ColorMatch™ Series offers the convenience of a 1A: 1B mix ratio by volume and has a very low viscosity. Demold times range from about 10 minutes to 2-4 hours (depending on product, mass and mold configuration). Note: Large mass castings will get very hot and shrink more, depending on mold configuration.
The ColorMatch™ Series also readily accept fillers (such as URE-FIL™ 3 from Smooth-On). Because of its neutral color, Smooth-Cast™ 325 is ideal for creating marble and wood grain casting effects, or duplicating the look of real metal by adding bronze, brass or other metal powder. Applications for the ColorMatch™ Series plastics include making pigmented prototype models or figures, special effect props, reproducing small to medium size sculptures, decorative jewelry, etc.
Used by artists and industry the world over for a variety of design, casting and special effects applications, PMC™-724 is by far the most versatile urethane rubber compound available on the market today. It is inexpensive, mixes and pours easily, and will cure to a durable rubber with negligible shrinkage. Low viscosity ensures flawless pick-up of even the finest detail with minimal bubble entrapment.
